Jamie Stephens is the acquaintance of killers Ricky Moss and Lou Olsen, as well as their unassuming lookout during the murder the duo committed. Stephens was tracked from the ID of Jake Lally he lifted for alcohol, which led to Ricky and Lou since the two went around with him bragging about the murder and Ricky was obsessed with Jake's sister Brenda.
Stephens was interrogated in custody, where he confessed to the ID theft and being a lookout, but he said he never believe the two would actually kill registered sex offender Kyle Jones. It's never specified if Stephens was arrested and charged. (CI: "Neighborhood Watch")
